Jessman,
T has been implicated in fusing the ends of your bones at a certain time of your development. Thats why those eunuchs of old grew excessively tall when they were castrated just before puberty. It depends on your genetics and your own body. Early pregnancy will stunt your growth as I seen myself. There are other hormones that are attributed to growth, but the doctors will not prescribe them anymore, even to certain dwarfs that need it to expand their frame to relieve the pressure of their normal growing organs. It had to do with ethics and the abuse from others that caused this ban. But with this, if your bones have already fused, that's it.
